Application tiled February t8. 1913, Serial No. 'Y-9,2m.

Be it known that I, Louis lli. Wine-nir, a eitizen of the United Cltates, residing at. New Haven, in the 'county otNew lleven -and State of Connecticut, have invented eerin a device ot' this character to prevent rotation ot the post. and that ivill also he avail able to increase the hearing1 sui-tare upon the sill plate.

To these, and other ends, my invention eonsists in the easement adjuster, having certain details of construction and conihi nations of parts, as will he hereinafer de scribed and'more particularly pointed out in the claims. v

Referring to the drawings, in which like numerals ot' reference designate like parts in the several figures; Figure 1 is a.,plan nnprovements thereon; Fig. 2 is an enlarged sectional view thereof upon line .fi-l of Fig. l; Fig. 3 is a similar view upon line C--D of Fig. l; Fig. et is a perspective view ot the post; and Fig. 'is a perspective view of the lock plate.

'lhe general design and structure of the easement adjuster as shown and described. herein, except as modified by niyinvention, the same as those now common in the art., there heiligv a sill plate l that lis secured to a. window sill, having,` a vslot 2 therein; a rod 3 pivotally and adjustahly secured at one end to the sill plate, and atitl'ie other end pivotally secured to the sash plate .-Li, thatJ is attached lio thefcaseinen't. windrnv. Heretot'ore there has heen ditticulty in hulding the post, to which the rod is connected with the base member, against rotation \vithin the sill plate, which very materially increasesthe longer the device is used`r the lparts being then morder vless worn and the sill plate, in many eases, loosened upon the siii to W iioh it 1s attached. When the post rotates, the sill A|olate end of the rod cannot i be securely held, and hence the easement Window is not locked against movement. In my invention I have provided a locking member that engages the post and sill plate and holds,l the post against rotation irrespeclive of' the measure ot' wear upon the parts, or the tightness ot the sill plate upon the vvindon' sill, ivhieh locking` member is desigj ed to prf the maximum frietion'surll plate. .l iv more particularly to my unimore-ments, the numeral 5 designates the post, havinge an elongated head li thereon, with the iets 8 in the opposite ends thereof, and an intermediate head i3 of substantially the saine width as the Slot 2. The lock plate il has a circular portion l0 with an opening diameter as the post 3, and lips l2 at each end, ot sahstantially the saine width the slm. 2. that tei-murale at their lower ends in 'the lingers iSv-13, of substantially the same .itilflth as die slots 5%. fithen assembled., the intermediate head T is `within the slot 2, the plate El upon the. post with the `portion lo restr-f upon the top of the sill plate,

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a device of the character described, the combination with the sill plate, having a slot therein; of a post within said slot; and a lock plate contacting with the top surface of said sill plate and having members thereon that pass 'through said slot and engage'the head of said post to prevent the rotation thereof whereby both said post and lock plate are held against relative rotation in said sill plate.

. 2. In a device of the character described, the combination With the sill plate, having a slot therein; of a post within said slot; and

a'lock plate upon said post contacting with the top surface of said sill plate and having a part thereon that passes through said slot and engages the head oit' said post to prevent the rotation thereof as Well as said lock plate.

3. In a device of the character' described, the combination with the sill plate, having a slot therein; of a. post within said slot, having a head .with a slot therein; and a lock plate contacting with the top-surface of' said sill plate and havingNa part thereon that passes through the slot in said sill plate and enters the slot in the said head to prevent rotation of said post and said lock plate.

4. In a device of the character described,

'the combination with the sill plate, having a slot therein; of a post Within said slot, having a slotted head thereon; and a lock plate upon the opposite side of said sill plate from said head, having parts thereon that pass through the slot. in said sill plate and enter the slots in said head to prevent rotation of said post and lock plate.

5 in a device of the character described, the combination with the sill plate, having a slot therein; of a post within said slot; and a lock plate upon said post, a portion of which is Wider than said slot and contacts with the upper surface of said sill plate, and having a lip thereon that projects through said slet and engages the head oi' said post to prevent the rotation thereof and said lock plate.

6. In a device of the character described, the combination with the sill plate, having a slot therein; of a post within said slot; and a lock plate contacting with the upper surface of said sill plate and terminating at each end in a lip that passes through said slot to prei-'ent the rotation of the lock plate, and said lips having a finger thereon that engages the head of said -post to prevent the rotation thereof of said post.

In testimony whereoic I affix my signature in presence ogt'two witnesses.
